Canon patent for 27x zoom Powershot camera (Powershot G3 X replacement?)


Canon patent for an optical formula that appears to refer to a possible Powershot camera. The patent is about a 9-240mm F2.8-5.6 lens that seems to fit a compact camera, a Canon Powershot. The optical formula resolves to a 27x zoom. 

The Canon PowerShot G3 X has a 25x zoom (24-600mm equivalent). May this patent refer to a replacement? It may be.
